- I rezaaot-ii I I i "and WALTER E. Gossnmqboth, citizens of.theUnitedStates, residing at Indianapolis,

in the county of Marion and State of'Indiana, have invented certain newand'u'seful Improvements 1n Storage Batter1es,of which the following 1sa full, clear, and exact descri tion. 1e invention upon which thisapplication for Le'tters Patent is based,'is an im-'provement'pertaining to storage batterles andinvolves a new means forsecuring the terminal posts of the electrodes in the cover .15for thecell, Whatever may beits material, but' more especially when such coversare composed of insulating, poorly conducting 5 or non-plasticsubstances. r For certain urposesexemplified in the Zoo-glass jar assemly of storage batteries used for house lighting, the use of hard rubbercovers has been almost universal, butsuch covers are not altogethersatisfactory because they are apt, undereven a relatively somewhatflexible and sag thus forming an X inadequate support for the batteryelements,

and becauseyunder present market conditions, proper covers of thisnature are diflicult to obtain.

This has. led us tothe use'of substitutes :for hard rubber, such asporcelain,'glass, or e,ven cast antimony-lead, and "other mate- .rials,which for practical reasons are necessarily such as will not be'injuriously at- .gtacked by dilute sulfuric acid; but the adop- 'tionof any substancehav'ing electric conductive properties or incapable ofbeing alteredin form by dies or tools or otherwise '40 fashioned whenonce molded and cooled, to meet the practical requirements of use whenterminal posts'are associated with them, has i'equired us to devise aspecial means for uniting the said posts to the covers and securing aliquid tight and durablejoint.

;We have accordingly made the improve- --ment on the means set forth anddescribed in our former Patent No. 1,251,452, dated December th, 1917,which we shall now proceed to'describe.

united to the cover the latter is" provided with asuitable" perforationsurrounded'by properlythickened walls or bosses C.

"D is a terminal post .in electrical union with the plates of agivenpolarity. Ithas an enlargement or flange-E to engage, with 1 'theundersidezof the'cover and is preferably enerally tapering form up tothe I part Whlll is united to the usual'connection.

I In applying this POSl/flt gasket-of relative *soft-Lor "compressiblematerial F is laid up against the edge of the opening in the cover,

and a washer G'ofwmore -rigid insulating material laid-upon it. Thepost} "then passed up through theopeniggand abushdown o'verthe'posta 1.7 y. ZThBbllShil'lgHBhOllld be'of suchmaterial then passed 1 as hardrubber. The gasket F should be of I softer and. more pliable materialsuch as 40% Para rubber.. While, the washer Gr especially if the coveris of any conducting material should be of hard rubber.

When these parts are assembled in the manner described 'a suitable toolis heated and applied to. the post or other means used to force out aflange K thereon and to cause it to sink intov the bushing in suchmanner as to bind'the lower flange E tightly against the washer G,maintain the gasket F under compression and at the same time force andhold the suitably shaped bushing into intimate contact with both postandcover. In

order that this gasket may the more perfectly eifect its intendedpurpose of securmg allquld tight joint, the under surface of thethickened boss G contains, a groove L into which the gasket is forced.

In this manner an inexpensive and effective liquid tight joint-issecured and .the

post, even should the gasket-F ultimately of an insulating sleeve,gasket-or the like;

between a cover and a conducting post is not a matter of invention, butthe peculiar exigencies of the storage battery art have offered manyproblems by no means easypf I solution, in the matter of making andmamtaining such joints in a practical manner. The means which we haveabove described have been found to fully answer this purpose.

What we claim is 1. The combination in a storage battery with a cellcover of'rigid material of a terminal post extending through a holetherein, said post having thereon a flange below the cover, a flangeformed integral therewith above the cover, an insulating bushing of hardmaterial surrounding the post Where it passes through the cover, and agasket of yielding material between the lowerflange and the edge of thehole in the cover, said gasket being compressed by the pressure of theupper flange on the bushing and the up"- ward pressureof the lowerflange into close union with the underside of the cover to form a tightjoint.

' 2. In a storage battery, the combination with a cover of rigidmaterial, of a terminal post e-Xtending'through a hole therein andformed with flanges above and below the said cover, a bushing ofhardened plastic insulating material, surrounding the post and overlyingthe ed e of the hole through which the post exten s,ia gasket ofyielding material between the under edge surface ofthe cover around thehole, a rigid -washer below the gasket, the pressure exerted upon thebushing and the washer by thetwo post flange, said gasket be'in .intothe groove and into intimate contact with the cover, and the bushingbeing forced into intimate contact with the cover, post and-gasket bythe pressure exerted by a suitabletool applied on'the upper portion ofthe post 4. In a storage battery the combination with a cover of rigidIn'ateriahof a terminal post extending through a hole therein, said postbeing formed 'with"integral flanges above and below, the "cover," andinsulating -material formed at least in part of yielding substanceinterposed between said cover and said post, the said insulatingmaterial being compressed into 'intiinate'contact' with the cover andthe post by'the pressure exerted a' suitable "tool brought "over theadjacent end of the post. i
